計法係「通勤公里數 × 11.1 ÷ 100 × 每度電價」。假設每日來回40公里，按標示耗電量計算會用約4.44度電；若每度電 HK$1.5，每日約 HK$6.66，返工22日約 HK$146.52。11.1kWh/100km屬車輛標示耗電量，電錶實際錄得嘅充電量通常仲會包含充電損耗，所以電費可能高少少；如果用公共充電，亦要另計服務費或充電站收費。實際金額應代入屋企電費計劃或充電站當時公布嘅價格。
Use this formula: commuting distance × 11.1 ÷ 100 × electricity rate. If the daily round trip is 40 km, the car’s stated consumption gives 4.44 kWh; at HK$1.50/kWh, that is HK$6.66 per day. Over 22 commuting days, the estimate is HK$146.52. The 11.1 kWh/100 km figure is the vehicle’s stated energy consumption, so the amount shown on the electricity bill may be higher because of charging losses. Public charging fees or service charges also need to be added separately. Actual cost should be calculated with the applicable home or charging-station tariff.
